Answer 1

#include<iostream>
#include<iomanip>
using namespace std;
int main(){

    char name[10][10];
    int regNum[10][2];
    cout<<"Enter the number of students:";
    int i,j,n;
    cin>>n;
    for(i=0;i<n;i++){
        cout<<"Name : ";
        cin>>name[i];
        cout<<"Registration number : ";
        cin>>regNum[i][0];
    }
    for(i=0;i<n;i++){
        regNum[i][1]=0;
        for(j=0;j<n;j++)
            if(regNum[i][0]<regNum[j][0])
                regNum[i][1]++;
    }
    for(i=0;i<n;i++)
        for(j=0;j<n;j++)
            if(regNum[j][1]==i)
                cout<<"Name : "<<setw(5)<<name[j]<<"  ,Registration number : "<<regNum[j][0]<<endl;

    return 0;
